Question

How do you graph (1,3) on a coordinate graph?

Answer 1

Hint: Coordinates are always written in brackets and within the bracket two numbers are separated by a comma. Coordinates are ordered pairs of numbers; the point on the x-axis is denoted by the first number and the point on the y-axis is denoted by the second number.

Complete step-by-step answer:
x-coordinate is a number on the x-axis, the x-coordinate is also called abscissa and y-coordinate is a number on the y-axis and the y-coordinate is also called ordinate. For plotting points on a graph, we have to first identify the quadrant in which the given point lays or the axis on which the point lies.

For the point (1,3) the x-coordinate is 1 and the y-coordinate is 3, both of the values are positive so this point lies in the first quadrant.
Below is the graph obtained on plotting this point in the coordinate graph –

Note: Two axes intersecting at right-angles form a graph; these two axes divide the graph into four quadrants. In the first quadrant, x-coordinates and y-coordinates are positive; in the second quadrant, x-coordinates are negative but y-coordinates are positive; in the third quadrant, both x and y-coordinates are negative and in the fourth quadrant, x-coordinates are positive but the y-coordinates are negative. In this question, the x and y-coordinate are positive so the point lies in the first quadrant. The origin is the point of intersection of the two axes.
